Small Businesses and Hobbies : Had fire on lot

Had fire during Home Business being open and now people keep coming in. I have had many many bug issues with the sims 4, all and all I tend to manage. However, this time around I am having some major game play issues outside of the usual graphics issues. I had my small business tattoo shop open, when my sims for some reason decided to do a barbeque outside. She caught the grill on fire and my sim ended up putting it out. The business force closed since there was a fire on the lot, however, since the fire my Small Business is basically open at all times....not to mention random sims are now just hoping into my "home" areas of the lot where the fire occurred, instead of sticking in the normal business lot areas. Has any one else had a fire on their lot when their small business was open and had this issue???? I really don't want to get rid of this save but its looking this way :(
